Siddhārtha Gautama was a spiritual teacher from ancient India who founded Buddhism.[1] In most Buddhist traditions, he is regarded as the Supreme Buddha of our age, "Buddha" meaning "awakened one" or "the enlightened one." .Gautama, also known as Śākyamuni or Shakyamuni ("sage of the Shakyas"), is the key figure in Buddhism, and accounts of his life, discourses, and monastic rules are believed by Buddhists to have been summarized after his death and memorized by his followers.
